1. How does species percent cover and diversity correlate with time since restoration?

Hypothesis: We will see increased exotic species percent cover and diversity with increased time since restoration.

1a. Total percent cover of exotics over time since restoration, by zone

Results: Increase in total exotic percent cover over time, driven by WT1, WT2, PH1, & especially RT.

1b. Exotic species richness over time, by zone

Results: Increase in exotic species richness over time, especially in the upland zone.

1c. Total percent cover of natives over time since restoration, by zone

Results: Increase in total native percent cover over time (but peak in years 3-5), driven by WT1, MS, & CS.

1d. Native species richness over time, by zone

Results: Native species richness increases over time.

## mapping: x = ~richness 
## geom_bar: na.rm = FALSE
## stat_bin: binwidth = NULL, bins = NULL, na.rm = FALSE, pad = FALSE
## position_stack

1e. Native:Exotic over time, by zone

Results:

2. Is seed bank contributing to increase in exotics?

Hypothesis: Exotic species in the seed bank will contribute to exotic percent cover.

2a. Exotic species in 2016 seed bank vs. exotic species in April/May 2017, by pool, by zone

Results: In the upland zone, more exotics species contributing to exotic percent cover than those that are in the seed bank

3. Compare to Del Sol data
